Document Description
The proposed project involves the construction and operation of a multi-depth monitoring well located on the Orange Coast College (OCC) campus in the City of Costa Mesa, California. The proposed 5-casing nested monitoring well would replace existing well OCWD-M43 that is currently maintained by Orange County Water District (OCWD) within the OCC campus. The purpose of the well is to monitor potential seawater intrusion and groundwater flow beneath the Newport Mesa. The existing monitoring we ll is located within the planned footprint development of a future student housing construct ion project and would be removed by OCC as part of a separate student housing project.
